The complication shows the min and max temperature today, the min and max temperature tomorrow, and the time the data was last refreshed (something missing from most complications imo). The color also tells you that there’s a good chance of rain today and tomorrow.
I’ve been using this myself for the last several months as we developed the app and I found it really useful. I hope you do too. Please let us know what you think. We value your feedback.
One note, right now due to the data source we use, this app only works for weather forecasts in the USA.
In this screenshot, the complication I designed is in the upper left corner and center circular bezel slot (the text around the dial).
